Clean the Front-End
Clean the mass spectrometer front-end using the routine cleaning method, to:
•
Minimize unscheduled system downtime.
•
Maintain optimum sensitivity.
•
Avoid more extensive cleaning that requires a service visit.
Symptoms of contamination:
Significant loss in sensitivity and increased background noise.
When contamination occurs, perform an initial routine cleaning. Clean up to and including the
front of the orifice plate. If routine cleaning does not resolve issues with sensitivity, a full cleaning
may be necessary.
This section provides instructions for performing routine cleaning without breaking vacuum and
full cleaning under atmospheric pressure, after venting the mass spectrometer.
Note:
Follow all applicable local regulations. For health and safety guidelines, refer to
Chemical Precautions on page 11
